In the past, many atmospheric scientists believed that pollen particles probably had a negligible effect on climate because they were so big. In recent years, however, as they began to realize that pollen ...

Taking part in the largest U.S. air quality field project in decades, the National Center for Atmospheric Research (NCAR) is working with partners to study pollution in the Southeast. The study looks at the ...

At any given time, cirrus clouds—the thin wisps of vapor that trail across the sky—cover nearly one-third of the globe. These clouds coalesce in the upper layers of the troposphere, often more than 10 ...

Ice covering the Arctic Ocean melted to the smallest areal extent ever recorded this year, falling to 1.3 million square miles at its lowest point on Sept. 16, according to the National Snow and Ice Data Cente ...

(Phys.org) -- The dramatic melt-off of Arctic sea ice due to climate change is hitting closer to home than millions of Americans might think. That's because melting Arctic sea ice can trigger a domino effect ...

Researchers in Finland have discovered that climate change has impacted various regions of the Arctic tundra by helping increase the levels of vegetation. Their data suggest that this rise could potentially ...

Anthropogenic climate warming is leading to consideration of options for geoengineering to offset rising carbon dioxide levels. One potential technique involves injecting artificial sea spray into the atmosphere. The sea ...

Engineering our way out of global climate warming may not be as easy as simply reducing the incoming solar energy, according to a team of University of Bristol and Penn State climate scientists. Designing the approach to ...

(PhysOrg.com) -- Tiny, ubiquitous particles in the atmosphere may play a profound role in regulating global climate. But the scientists who study these particles -- called aerosols -- have long struggled to ...
